For distributed, decentralized, impossible-to-censor search engines: Yacy ( https://yacy.net/en/index.html ) - currently it works pretty poorly. Every time I tried it, it ran but gave me junk results.

For distributed, decentralized, server resource hosting for web applications: SAFE Network ( https://safenetwork.tech/ ) - some places group it with cryptocurrencies but the concepts behind it are different and it might be feasible. I'm watching it but not trying to use it yet.

And I like the idea of secure, untraceable currency transactions through cryptocurrencies but most existing cryptocurrencies are just energy-intensive pyramid schemes.

Many other similar such projects in all kinds of categories exist. But none have reached the "click to install and go!" stage.
